Following in the footsteps of the SQ5 performance crossover, the SQ2 and SQ4 nameplates would seem to indicate that Audi is planning performance versions of its upcoming compact crossovers. The Q9 would suggest that a larger crossover is in the works to slot in above the already gargantuan Q7. And the F-Tron name could be used for a fuel-cell version of the A7 or other models, following a similar naming pattern to the E-Tron range of electric vehicles.
Of course Audi could simply be filing these trademarks as a safeguard and may not actually build any of these models. But one way or another, it indicates a certain measure of intent exists as Ingolstadt gears up to expand its lineup with 11 new models in the next few years.
